Fuel Tank and Lines

FUEL TANK AND LINES

The fuel system consists of:
- the fuel tank assembly.
- the fuel tank filler pipe, which contains a restrictor plate to permit only unleaded fuel to be pumped into the fuel tank.
- a 1/4 turn type fuel tank filler cap.
- a fuel filter to protect the fuel injectors located on the fuel tank assembly.
- fuel tube.
- fuel rail pressure and temperature sensor, located on the fuel rail.
- a fuel pump containing:
- the electric fuel pump, which provides pressurized fuel to the engine.
- the fuel level sensor.
- an inlet filter.
- a check valve which maintains system pressure after the pump is shut off.
- a pressure relief valve for overpressure protection in the event of restricted flow.

The fuel pump is controlled by the powertrain control module (PCM). Electrical power to the pump is provided through the inertia fuel shutoff (IFS) switch.
